An old classmate sent a circle of friends to travel. I made a comment and asked a question. I am very unhappy that my old classmates didn't reply. Excuse me, everyone,

I think your relationship with this old classmate is not generally good, which also shows that you are very kind. If it is an ordinary classmate relationship, it means that TA has something to reply at the first time, which means that TA has more important things to do than replying to you. If it's not an ordinary classmate relationship, first of all, it means that TA has something to do, and secondly, TA can't reply to your questions in public. I hope you can roughly understand what I said.
